Mating dance for nesting
Nesting has been anticipated for quite some time, with lots of speculation about how the mechanic will work, many players are quite enthusiastic about nesting when it comes.
It would be nice to have a Mating Dance mechanic. Just a single 1 button emote that shows a player you're interested in mating. Just like the group invite or remove call, it'd be nice to have a mating dance/mating request.
